Biology Research

James Koukl - The Turtle Research Laboratory

My research interests encompasses the ecology, behavior, physiology, and conservation of box turtles and freshwater aquatic turtles. I am particularly interested in the correlation in the box turtle's physiological changes and their behavior. My research focuses in the area of behavioral and physiological ecology and has included work on hibernation physiology and radiotelemetry.

Undergraduate Students

I am looking for serious undergraduate students who have a high degree of curiosity, commitment, and strong work ethic to work with turtles in the field and the turtle lab. Students must be hardy enough to work in the field with the heat and rain without complaint. Students can expect to develop and conduct an independent research project focusing on the biology and or conservation of turtles. Students can expect to develop an expertise and working knowledge of the literature relating to the student's chosen research topic. Students will also become familiar with scientific writing, publications, and peer-review process by helping produce a publishable manuscript describing the results of the student's research project. Students should plan on meeting with me regularly at other times throughout the semester as you work on your projects. As a part of this research experience undergraduate students will learn how to produce a professional CV, getting into graduate schools, giving presentations and making posters, writing grant proposals, selecting appropriate journals for submitting manuscripts, letters of recommendation, and the peer-review process.

Undergraduate funding generally comes from research assistant appointments depending on the particular grant.

Graduate Students

I will take up to two masters level students per year. Most of all my past graduate students that

have worked in my lab have had studied amphibians or reptiles. Most all projects involve a field component. I am looking for master's level graduate students who have a high degree of interest in a career in organismal biology. They must have a strong work ethic and willingness to work evenings, weekends, and holidays if necessary. Graduate students must have good communications skills, especially writing, and good technical skills in the field and be self starters. Graduate students must have moderate to good grades and good GRE scores.

If you are interested in MS level graduate studies send me a description of your professional interests, career goals, copy of your CV/resume and contact information for references. Send your GPA for all you undergraduate course work as well as GRE scores both the general and biology exams.

Arrange for a time when I can contact you and discuss whether you should apply to my lab. After reviewing your credentials and talking with you I will let you know if I think you should formally apply to our graduate program.† In the Department of Biology it is necessary for a faculty member to agree to accept a student before they are admitted to the graduate program.

Funding for Graduate students comes from $10,000 per year teaching assistantships (TA's) for teaching two general biology labs per semester and from grants.
